Per the guidelines here's the info on my bike and myself:
It's an '87 with 36K miles on it. I did the belt to chain drive conversion. Did the verslavy mod (i think that's what someone called it) to the timing chain tensioner at around 17K miles. didn't know it was a common mod and that it even had a name... at the time it was just a logical "temporary" fix i came up with but i guess it's a keeper... (unlike some other ill-advised temp fixes that I've come up with) ... that's it, as far as modifications go. I know a thing or two about especially automotive mechanics although I don't do it for a living.
So recently i changed the timing chain and refurbished the rocker arm tappets. The problem was, i put it all back together, It starts without a problem, but when i go full throttle, it will rev all the way up nicely and then it sort of chokes and revs down for about half a second, then revs up for half a second, down, up, down, up ... the whole time, the throttle is wide open, also backfires randomly during the process. The up-down revving seems to have a steady frequency, half second up, half second down ish... but the backfiring happens randomly. i suspect either the carb caught some dirt or something while i was fixing the other stuff. Or i got the timing wrong. That brings me to something else... Is there any timing mark on the other side of the crankshaft? the right side, if you're sitting on the bike i mean.... Because i can't see the mark on the left side... i see the groove on the inside of the hole where you unscrew that big round cap but not the mark behind the crankshaft bolt, it literally looks like someone filed it off.... So i found TDC by rotating and feeling the piston in the up position... But i noticed the piston stays up for a little bit even if you continue to rotate a few degrees... or I thought it did.... plus, i was rotating the crankshaft clockwise to find TDC... i've read that you're supposed to do it counter clockwise so i'm mentioning that so someone might be very kind and explain why it makes a difference.
Another thing is that, even without letting it reach the point where it starts giving this problem, i.e. without going full throttle... it just feels slower, lazier... It could be that i'm using a Honda CX650 as a backup bike in the meantime (faster) so now my savage feels slow... but it doesn't feel quite right. and given the symptoms... could the timing be a bit off? should i start by cleaning the carb? I'd appreciate any help.
